Outline

• Introduction
• Distributed System Architecture (Three units)
• Real-Time Video Streaming Case
• Conclusions

Introduction
Specific device, stream formats, resolution
4
Distributed System Architecture
These three units are designed as loose-coupling
architecture
One stream, multiple purposes
Image Processor
Presentation unit
Capture unit
5
Three-tier architecture (1/3)
Capture unit Image Processor Presentation unit

Video input (Device/Interface) Format (Tool/Stream Format)
HDV(1394) HD/MPEG-2TS
DV(1394) DVTS/RAW DV
WEB-CAM(USB) VLC/MPEG-4
CABLE (CAPTURE CARD) VLC/MPEG-4
HD, DVTS, and VLC are open source software
6
Three-tier architecture (2/3)

• Stream Receiver VLC FFMPGE
• Image Processor
• stream clipping
• image processing
• image management
• Image Navigation security control

Three-tier architecture (3/3)
Capture unit Image Processor Presentation unit

• Can view the video from web browser or standalone
  version
• The historical monitoring window

8
Distributed stream compression

• Two compression concepts have been implemented
• Client-Server based
• Reduces network bandwidth
• Transfers video stream to multi-formats(mp4,wmv,fl
  v,mjpeg)
• Server-side based
• Dynamically assign the video stream to suitable
  servers depending on loading.
• Compresses the video stream to a variety of
  bit-rates for different network bandwidth

Distributed stream compression

• Native VS With compression concepts

Conclusion

• Has been proofed in real time high-resolution
  ecological observation
• Plug and Stream
• Loosely coupled architecture, easy to scale-up
• Support multiple streaming methods
• Based on open source software, no hi-end hardware
  required.
